Eye Drops for Allergies

Eye drops designed for ocular allergies can provide relief from bothersome symptoms. They may also take some time to work.

For individuals with sensitivities to drops, or the components in them, the eye may feel strange when the drops are used. If there is more than just temporary, mild burning, or stinging, the drops may need to be discontinued. Always check with your doctor before starting or stopping any eye medications.

Some eye drops for allergies contain benzalkonium chloride (BAK), a preservative that can be harmful to the eye. (BAK is also used as a preservative in OTC lubricating drops and ointments. View our list of commonly available Lubricating Drops and Ointments to see which of these products contain BAK).

If you experience stinging when using eye drops for your allergies, see how to instill drops for tips on how to prevent stinging when using eye drops.
